Integrative Use of Sound Therapy for Mental Health Promotion

Integrative Use of Sound Therapy for Mental Health Promotion: A Randomized Clinical Trial

This randomized clinical trial aims to evaluate the effectiveness of sound therapy in improving mental health and quality of life. Participants will be randomized into two groups: an intervention group using an acoustic resonance chamber and a control group using headphones. Both groups will be exposed to specific sound frequencies for nine minutes, once a week, for three weeks. The study investigates associations between sound therapy and levels of anxiety, stress, depression, and quality of life.

• Mental health disorders such as anxiety, stress, and depression are prevalent global health issues. Sound therapy is proposed as an integrative complementary therapy to address these conditions. This prospective randomized open-label study involves 110 participants.
• Participants will be randomized into:

> 1. *Intervention Group:* Receives sound therapy inside a specifically designed acoustic resonance chamber.

> 2. *Control Group:* Receives the same sound therapy sequence using headphones, without the chamber.

• The intervention consists of three weekly sessions of 9 minutes each. The sound protocol uses nine specific frequencies (ranging from 174 Hz to 936 Hz) derived from a 432 Hz tuning reference. Outcomes will be measured using validated scales including DASS-21, WHOQOL-Bref, and others at baseline, during the intervention, and at 30-day and 120-day follow-ups.
